Post foglight lens polish and additional stone guards?

Ok, so I'm going to be putting the trim stuff back on my car after the repaint, and the foglight lenses are pretty well sandblasted. Is there a way to polish them up some?

In addition, after the 6 original stoneguards are applied, would it not be a good idea to cut some 3M material for the mirrors and the foglights as well?

I wonder if you could put Tear-offs on them kind of like Motorcycle racers on their helmets.

You can get the Stonegard sets from Tweeks for about $50 for the whole front end light set. I have them on my S2. It's a one time deal, put them on and then forget about it. Performance Products may also carry them.

Ok I apologize it is still early. I mean once you get it clean. I have heard or people trying to polish them but don't know how they did it.

Can't you buy kits to polish the pits out of a windsheild? Maybe something like that would do it.

Didn't you get Iceshark's kit? If so let me know when you get your car back I would like to see how well those headlights work.

Yes, Keith got the full headlight package.

As far as polishing the sandblasting out, it can be done but you are going to put waves in the glass surface and probably change the optics a bit. I don't think this would be a serious problem for a short range light like the fog, though the driving side could be a problem. Given the replacement cost, give it a shot on the fog side. Do a google search and you can find polishing kits.

If you get the plastic guards don't go running overwatted bulbs. You will melt the plastic.

Tabo, read up on how the DIY telescope guys build their own mirrors. They have a bunch of great tips on how to polish correctly and keep dimensions. If you do this right, it will be better than new, though a bit thinner and more prone to a rock than originally intended.

Takes a long time though. There is a reason it takes *years* to shape and polish up a big telescope lens. But you ain't trying to look out millions of light years.

I've been thinking of tossing the original fogs (lens are pitted and the reflectors are brown) and putting in the new small Hella DE Fogs...is there anything back there (in a '87 NA) to mount them to?

Steve,

There is nothing to mount them to. The hells's usualy mount at the bottom of the light on a pivot

You could mount them however, it may require some drilling.

If someone has purchased the Stoneguard kit recently, they should save the paper backings that they were attached to. I have a guy here in town that said he has the clear 3M material used to make them with. The stuff is very cheap but he needs a stencil. I don't know why nobody hasn't tried doing this before. Cost is somewhere around $15.

There is a deep scratch pro repair kit for glass available from Eastwood Unique Automotive Tools and Supplies catalog (www.eastwoodcompany.com) that will polish the lenses. The warning is that it does take a layer of glass off so the waviness can be tradeoff. Short of that, every other polish I tried (Meguire's etc) just didn't produce the desired results on the 944 lenses. Keep in mind new lenses are about $100 ea and complete units are $250, the $45 for the kit may not be a bad deal. I ended up buying the Bosch fog/driving light combo for about $250 for the pair at auction - I liked the idea of utilizing full capabilities the 944S2 intended.

I had a hole in one of my 951 foglights.Got a used one very cheap, but unfortunately it was like sandblasted.
I have during the years tried all kinds of automotive stuff to polish glass.Most of them does not work as they should.
A relative of mine is keen of all kind of space stuff.He has made his own telescope, including all of the optics.He gave me some powders which are used for making telescope lenses.I tried yesterday evening these powders and they do WORK!
They are also very cheap, only few euros / bottle.There are lots of different grades available.I am using as a tool very thick pieces of plastic, which are ment to eye glass lense manufacturing.I am expecting to have all of the scrathes removed.

They are not necessary any products.At least i don't know if they have any trademarks.
The stuff is the following:

Aluminiumoxide (different grades)
Ceriumoxide (different grades)
Pi carbide
Cobblers' wax.

I have just made few exprerimentals, but this stuff seams to work.
I would suggest you to find out the local "space-telescope" guys.They can help you to choose the right stuff & procedurs.This relative of mine will be arrange a "hands-on traing" for me.What comes to these telescope lenses, it was very time consuming procedure, it took several months ! Luckily 951 fog-lamps are much less work !
